SSC CGL 2024 PYQ — Question 64

The correct answer is option 2 i.e. $81\sqrt3$.

The area of an equilateral triangle with side length 's' is given by:

Area = ($\sqrt{3}$/4) × s$^2$

In this case, the side length (s) is 18 cm. So, we substitute this value into the formula:

⇒ Area = ($\sqrt{3}$/4) × (18)$^2$

⇒ Area = ($\sqrt{3}$/4) × 324

⇒ Area = 81$\sqrt{3}$ cm$^2$

Therefore, the area of the equilateral triangle is 81√3 square centimeters.
